Problems:
SISPI interlock kept breaking over and over again starting at UT 00:10. Problem was identified as miscomunnication between SISPI and telescope shutter. After multiple tries, a full system restart was done by telescope operators. We regained control around UT 02:31 and started our exposures again. We lost about 20 minutes of observing time
Network issues on the mountain made the remote control via Keeper impossible. So, we had to resort to zoom remote control and remote control via old VNC in Tucson observing room
